assignassignAssignAssign (Operator)

Name

assignassignAssignAssign — Assign a new value to a variable.

Signature

Description

assignassignAssignAssignAssign assigns a new value to a variable.

In the full text editor, an assignment is simply entered with the help of the assignment operator :=, e.g.:

  u := sin(x) + cos(y)

This is equivalent to the C syntax assignment:

  u = sin(x) + cos(y);

If the operator window is used for entering an assignment, assign must be entered into the operator combo box as an operator name. This opens the parameter area, where the parameter InputInputInputInputinput represents the expression that has to be evaluated to one value and assigned to the variable, i.e., this is the right side of the assignment. The parameter ResultResultResultResultresult gets the name of the variable, i.e., this is the left side of assignment.

Attention

In addition to the parameter type control, which is indicated in the parameter description, assignassignAssignAssignAssign also supports iconic variables and vector variables. For an assignment, the parameter types of the two parameters InputInputInputInputinput and ResultResultResultResultresult must be identical. For the assignment of iconic objects, the operator copy_objcopy_objCopyObjCopyObjCopyObj is used internally.

Parameters

Example (HDevelop)

Tuple1 := [1,0,3,4,5,6,7,8,9]
Val := sin(1.2) + cos(1.2)
Tuple2 := []

Result

If the expression is correct assignassignAssignAssignAssign returns 2 (H_MSG_TRUE). Otherwise an exception is raised and an error code returned.
